| **WARNING:** following documentation is from old sources, and is possibly |
| not representative of OPALv3 as implemented by skiboot. This should be |
| used as a starting point for full documentation. |
| |
| The host calls this function to bind a PE to an XIVE. Only that PE may then |
| signal an MSI that selects this XIVE. |
| |
| ``phb_id`` |
| is the value from the PHB node ibm,opal-phbid property. |
| |
| ``pe_number`` |
| is the index of a PE, from 0 to ibm,opal-num-pes minus 1. |
| |
| ``xive_number`` |
| is the index, from 0 to ibm,opal,ibm-num-msis minus (num_lsis+1) |
| |
| This call maps the XIVR indexed by xive_num to the PE specified by |
| pe_number. For ibm,opal-ioda HW, the pe_number must match the pe_number |
| set in the MVE. |
| |
| Return value: |

| .. code-block:: c |

| if (!phb) |
| return OPAL_PARAMETER; |
| if (!phb->ops->set_xive_pe) |
| return OPAL_UNSUPPORTED; |
